Abstract

Security systems and methods of operating the same. One security system includes a plurality of point devices positioned in a premises, a plurality of interim devices, and a control panel. The system also includes a first communication bus connecting the control panel and each of the plurality of interim devices and a plurality of second communication buses. Each of the plurality of second communication buses connects one of the plurality of interim devices with at least one of the plurality of point devices. The control panel is also configured to address a message for one of the plurality of point device based on an identifier of the one of the plurality of point devices and an identifier of at least one of the plurality of interim devices connected to the point device over one of the plurality of second communication buses.

Claims

1. A security system comprising:

a plurality of point devices positioned in a premises;

a plurality of interim devices;

a control panel;

a first communication bus connecting the control panel and each of the plurality of interim devices; and

a plurality of second communication buses, each of the plurality of second communication buses connecting one of the plurality of interim devices with at least one of the plurality of point devices,

the control panel configured to address a message for one of the plurality of point device based on an identifier of the one of the plurality of point devices and an identifier of at least one of the plurality of interim devices connected to the point device over one of the plurality of second communication buses.

2. The security system of claim 1, wherein the plurality of point devices includes at least one input device receiving input from the environment of the premises.

3. The security system of claim 2, wherein the at least one input device includes at least one selected from the group comprising of a motion detector, a panic button, a smoke detector, a water sensor, a flow switch, and an image sensor.

4. The security system of claim 1, wherein the plurality of point devices includes at least one output device providing output to the environment of the premises.

5. The security system of claim 4, wherein the at least one output devices includes at least one selected from the group comprising of a relay, a siren, a door strike, and a strobe.

6. The security system of claim 1, wherein the plurality of interim devices includes a plurality of interface devices configured to interface with a user located on the premises.

7. The security system of claim 6, wherein the plurality of interface devices includes at least one selected from the group comprising of an access reader, a keypad, and a keyswitch.

8. The security system of claim 1, wherein each of the plurality of second communication buses connects one of the plurality of interim devices with each of the plurality of point devices located closest to the one of the plurality interim devices than the remaining plurality of interim devices.

9. The security system of claim 1, wherein the control panel is configured to automatically assign each point device connected to one of the plurality of interim devices to an area of the premises for configuration purposes.

10. The security system of claim 8, wherein the control panel is configured to receive a manual adjustment to the automatic assignment for at least one of the plurality of point devices.

11. The security system of claim 1, wherein the message is addressed based on a plurality of interim devices, wherein each interim device is connected downstream of the control panel and upstream of the point device.

12. The security system of claim 1, wherein the control panel is not directly connected to the plurality of second communication buses.

13. A method of communicating with a point device connected to a control panel included in a security system, the method comprising:

addressing, at the control panel, a message to the point device based on an identifier of the point device and an identifier of an interim device connected to the point device;

transmitting, at the control panel, the message to the interim device over a first communication bus; and

transmitting the message from the interim device to the point device over a second communication bus, wherein the control panel is not directly connected to the second communication bus.

14. The method of claim 13, wherein transmitting the message to the first interim device includes transmitting the message from the control panel to a second interim device and transmitting the message from the second interim device to the first interim device over the first communication.

15. A security system comprising:

a control panel;

a first communication bus connecting a control panel and each of the plurality of interim devices positioned in a premises being monitored by the security system; and

a plurality of second communication buses, each of the plurality of second communication buses connecting one of the plurality of interim devices with at least one of a plurality of point devices located closest to the one of the plurality of interim devices within the premises,

the control panel configured to address each of the plurality of point devices based on an identifier associated with each point device and an identifier associated with the interim device connected to the point device over one of the plurality of second communication buses.

16. The security system of claim 15, wherein the control panel is configured to automatically assign each point device connected to one of the plurality of interim devices to an area of the premises for system configuration purposes.

17. The security system of claim 16, wherein the control panel is configured to receive a manual adjustment to the automatic assignment for at least one of the plurality of point devices.

18. The security system of claim 15, wherein the message is addressed based on a plurality of interim devices, wherein each interim device is connected downstream of the control panel and upstream of the point device.

19. The security system of claim 15, wherein the control panel is not directly connected to the plurality of second communication buses.
